[Gabor Grothendieck]

Try chron:

> library(chron)
> namefile <- "070707050642.dat"    #day-month-year-hour-minute-second.dat
> x <- chron(substr(namefile, 1, 6), substr(namefile, 7, 12),
+   format = c("dmy", "hms"), out.format = c("m/d/y", "h:m:s"))
> c(x, x)
[1] (07/07/07 05:06:42) (07/07/07 05:06:42)
